919e14f01e sed: Try hard links to make -i target available continually.
When creating a backup file, sed renamed the original before renaming the
changed copy into place, leading to a short time when no file with the
original name was present (usually only visible on SMP systems). Try
creating the backup file using a hard link instead, avoiding this problem.
If creating the hard link fails for any reason, fall back to the old rename
method.

When not creating a backup file, sed already renamed the changed copy onto
the original. This remains unchanged.

I am not adding the suppression of redundant fchown/fchmod to this commit,
because FreeBSD appears to check this in the kernel (for msdosfs at least).

ac8f32ce62 IEEE Std 1003.1, 2004 Edition states:
"The escape sequence '\n' shall match a <newline> embedded in
the pattern space."

It is unclear whether this also applies to a \n embedded in a
character class.  Disable the existing handling of \n in a character
class following Mac OS X, GNU sed version 4.1.5 with --posix, and
SunOS 5.10 /usr/bin/sed.

backslash if he/she wants to use a non-traditional delimiter, i.e.,
anything other than a slash.  That is, /abc/ works as is, but xabcx
needs to be spelled as \xabcx.

Add appropriate markup.

d3e5e11ce6 WARNS fixes:
1) Add missing parens around assignment that is compared to zero.
2) Make some variables that only take non-negative values unsigned.
3) Some casts/type changes to fix other constness warnings.
4) Make one variable a const char *.
5) Make sure termwidth is positive, it doesn't make sense for it to be negative.

870945d830 Before doing compile_re() which needs a parameter to identify
whether we should ignore case, determine the flag by calling
compile_flags() first.  Also, make sure that we obtain an
initialized cmd->u.s buffer before processing further.  We
may want to refine this solution later, but for now, make
the changes in order to unbreak world build after a sed(1)
with rev. 1.29 of compile.c is installed.

f6703c9c0a Change the semantics of -i (in-place editing) so that it treats
each file independently from other files.  The new semantics are
desired in the most of practical cases, e.g.: delete lines 5-9
from each file.

Keep the previous semantics of -i under a new option, -I, which
uses a single continuous address space covering all files to edit
in-place -- they are too cool to just drop them.

Add regression tests for -i and -I.

6b8ef68111 This trivial change should fix at least 3 similar bugs. All of
them are related to the `c' function's need to know if we are at
the actual end of the address range.  (It must print the text not
earlier than the whole pattern space was deleted.)  It appears the
only sed function with this requirement.

There is `lastaddr' set by applies(), which is to notify the `c'
function, but it can't always help because it's false when we are
hitting the end of file early.  There is also a bug in applies()
due to which `lastaddr' isn't set to true on degenerate ranges such
as `$,$' or `N,$' if N appears the last line number.

Handling early EOF condition in applies() could look more logical,
but it would effectively revert sed to the unreasonable behaviour
rev. 1.26 of main.c fought against, as it would require lastline()
be called for each line within each address range.  So it's better
to call lastline() only if needed by the `c' function.

Together with this change to sed go regression tests for the bugs
fixed (c1-c3).  A basic test of `c' (c0) is also added as it helped
me to spot my own error.
